Final answer:
The best statement reflecting a nurse's attention to a client's need for self-efficacy is the one expressing confidence in the client's ability to use an inhaler after a demonstration. It directly supports the concept of self-efficacy, which is crucial for patients managing their health.
Step-by-step explanation:
The statement that best reflects a nurse's appropriate attention to a client's need for self-efficacy is: "After you watch me demonstrate this inhaler, you will have no problems using it at all." This statement implies that the nurse is confident in the patient's ability to perform the task themselves after being shown how to do it, which in turn can bolster the patient's own confidence in their ability to manage their health. Self-efficacy refers to a person's belief in their capacity to execute behaviors necessary to produce specific performance attainments.
